Ultrastrong and Thermo‐Remoldable Lignin‐Based Polyurethane Foam Insulation with Active‐Passive Fire Resistance

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(40)

Published: June 19, 2024

Abstract Foam thermal insulators are indispensable for prevailing energy‐saving engineering, however their widespread use brings intractability such as unsustainability, “white pollution”, and fire hazards. The emergence of bio‐based foams is highly appreciated, but the fabrication approaches economically unattractive and/or product properties inferior, making large‐scale implementation unviable. Herein, a versatile, thermally remoldable phosphate‐containing polyurethane composite foam (LPU‐G) constructed from natural lignin expanded graphite flakes via an atmospheric pressure scalable one‐pot strategy. optimal LPU‐G exhibits exceptional mechanical strength, capable supporting over 6000 times its weight without significant deformation. Moreover, demonstrates desired multifunctionality in handling extreme circumstances, including humidity‐tolerant insulation, superb water vapor barrier, withstanding ≈1200 °C flame ignition. Based on “expansion‐conductivity” micro‐mechanism, first material to be sensitive alarm system with ultra‐long time (>1800 s). Surprisingly, can rapidly upcycled into recyclable bulk composites second life through simple thermo‐molding processes rooted multi‐dynamic behavior phosphate, carbamate, hydrogen bonds. easy‐to‐scale represents new generation that address concerns regarding high cost, risk, inferior properties.

Fire‐Safe Aerogels and Foams for Thermal Insulation: From Materials to Properties

Advanced Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 19, 2024

The ambition of human beings to create a comfortable environment for work and life in sustainable way has triggered great need advanced thermal insulation materials past decades. Aerogels foams present prospects as insulators owing their low density, good insulation, mechanical robustness, even high fire resistance. These merits make them suitable many real-world applications, such energy-saving building materials, thermally protective aircrafts battery, warming fabrics. Despite advances, date there remains lack comprehensive yet critical review on the materials. Herein, recent progresses fire-safe thermal-insulating aerogels are summarized, pros/cons three major categories aerogels/foams (inorganic, organic hybrids) discussed. Finally, key challenges associated with existing discussed some future opportunities proposed. This is expected expedite development insulating help sustainable, safe, energy-efficient society.
